Question 1

What is certified payroll?

Accepted Answer

Certified payroll is a weekly payroll report that contractors and subcontractors on federally funded construction projects must submit to the contracting agency. Required under the Davis-Bacon Act (40 U.S.C. § 3141), the report documents each worker's name, classification, hours worked, wages paid and fringe benefits. The standard federal form is the WH-347. The report includes a signed statement of compliance certifying that the information is accurate and that workers were paid at least the prevailing wage rate. For a deeper explanation, see certified payroll guide for contractors.

Question 2

What is the difference between payroll and certified payroll?

Accepted Answer

Standard payroll is an internal business function; you calculate wages, withhold taxes and pay employees. It has no public submission requirement. Certified payroll adds a compliance layer: you must submit a weekly report (typically WH-347) to the contracting agency, listing every worker's classification, hours and wages on the covered project, along with a signed statement of compliance. The certified report becomes a public record subject to audit by the U.S. Department of Labor Wage and Hour Division (WHD) or a state agency. Standard payroll stays between you and your employees; certified payroll is between you and the government.

Question 3

Why is certified payroll required?

Accepted Answer

Certified payroll exists to protect construction workers on publicly funded projects from wage underpayment. The Davis-Bacon Act, enacted in 1931, requires contractors to pay locally prevailing wages on federal construction contracts. Certified payroll is the enforcement mechanism: by requiring weekly, signed reports, the government creates a paper trail that auditors can check against wage determinations. Without it, there is no reliable way to verify that workers building roads, schools and government buildings actually received the wages they were owed.

Question 4

When is certified payroll required for construction?

Accepted Answer

Certified payroll is required on federal construction contracts exceeding $2,000 for construction, alteration or repair of public buildings or public works under the Davis-Bacon Act. Many state prevailing wage laws set their own thresholds. For example, California requires certified payroll on all state-funded public-works projects regardless of dollar amount under Labor Code § 1776. If your project receives any federal funding and exceeds the $2,000 threshold, Davis-Bacon certified payroll requirements apply. Some projects trigger both federal and state requirements simultaneously. See certified payroll trigger thresholds by project type for a full breakdown.

Question 5

Which law requires a company with federal contracts to use certified payroll?

Accepted Answer

The Davis-Bacon Act (40 U.S.C. § 3141 et seq.) is the federal statute that requires certified payroll on covered construction contracts. The U.S. Department of Labor Wage and Hour Division (WHD) enforces the law. Related statutes extend Davis-Bacon requirements to projects receiving federal assistance, such as highway construction funded through the Federal-Aid Highway Act. The implementing regulations at 29 C.F.R. Part 5 spell out the weekly reporting, recordkeeping and statement-of-compliance requirements that contractors must follow.

Question 6

What is the difference between state prevailing wages and Davis-Bacon Act wages?

Accepted Answer

Davis-Bacon wages apply to federally funded construction projects and are set by the U.S. Department of Labor by county, project type and worker classification. State prevailing wage laws, such as California's Labor Code § 1720, apply to state-funded public-works projects and are set by the state agency. State rates may be higher or lower than federal rates for the same classification in the same county. When a project receives both federal and state funding, the contractor must pay whichever rate is higher. The forms, submission schedules and enforcement agencies also differ by jurisdiction.

Question 7

What is the difference between certified payroll and Davis-Bacon?

Accepted Answer

Davis-Bacon is the federal law (40 U.S.C. § 3141) that requires contractors on covered projects to pay prevailing wages. Certified payroll is the reporting mechanism that proves compliance with that law. Think of Davis-Bacon as the rule and the WH-347 certified payroll report as the receipt. You can have Davis-Bacon obligations without submitting certified payroll only if you are below the contract threshold, which is rare on federal projects. In practice, the two go hand in hand on every covered contract.

Question 8

What is California DIR certified payroll?

Accepted Answer

California DIR certified payroll refers to the certified payroll reports required by the California Department of Industrial Relations on state-funded public-works projects under Labor Code § 1776. California uses its own electronic certified payroll reporting (eCPR) system, which contractors must use to submit reports directly to DIR. The state's requirements differ from federal Davis-Bacon rules in format, submission frequency and enforcement. California also requires contractor registration with DIR before bidding on public-works projects. For state-specific guidance, see California DIR certified payroll requirements.

Question 9

What is the certified payroll form WH-347?

Accepted Answer

Form WH-347 is the standard certified payroll form issued by the U.S. Department of Labor for Davis-Bacon-covered projects. It is submitted weekly and includes columns for each worker's name, address, classification, hours worked each day, total hours, rate of pay, gross wages, deductions and net wages. The form has two parts: Part I is the payroll data and Part II is the Statement of Compliance, which must be signed by a principal of the contractor or subcontractor. While use of WH-347 is not technically mandatory, most contracting agencies require it or an equivalent format.

Question 10

What is a statement of compliance for certified payroll?

Accepted Answer

The statement of compliance is Part II of Form WH-347. It is a signed declaration by a principal of the contractor or subcontractor certifying that the payroll data is correct and complete, that prevailing wages were paid, that classifications are accurate and that any apprentices are properly registered. The signature is made under penalty of perjury. Submitting a WH-347 without a signed statement of compliance is one of the most common audit-triggering errors. A missing or unsigned statement can result in the entire weekly submission being rejected.

Question 11

Does certified payroll need to be signed?

Accepted Answer

Yes. Under 29 C.F.R. § 5.5(a)(3)(ii), the statement of compliance on the certified payroll report must be signed by a principal of the contractor or subcontractor, such as an owner, partner or corporate officer. The signature certifies the accuracy of the payroll data under penalty of perjury. An unsigned report is treated as incomplete. Some contracting agencies accept electronic signatures, but you should confirm the acceptable format with your specific agency before submitting.

Question 12

Who is exempt from certified payroll?

Accepted Answer

Bona fide executive, administrative and professional employees exempt under 29 C.F.R. § 541 are generally not subject to certified payroll reporting. Material suppliers who do not perform on-site construction work are also exempt. Projects below the $2,000 federal contract threshold fall outside Davis-Bacon coverage entirely. However, any laborer or mechanic working on a covered project site must be reported, regardless of whether they work for the prime contractor or a subcontractor at any tier.

Question 13

How do you handle certified payroll for 1099 workers?

Accepted Answer

Misclassifying W-2 employees as 1099 independent contractors to avoid prevailing wage obligations is one of the most common Davis-Bacon violations flagged in WHD audits. True independent contractors who meet the economic-reality test may be exempt from certified payroll reporting, but the bar is high. If a worker is economically dependent on the contractor, takes direction on how to perform the work and uses the contractor's tools or equipment, they are likely an employee regardless of their 1099 status. Getting this wrong exposes you to back-wage liability, penalties and potential debarment.

Question 14

How do you determine Davis-Bacon wages?

Accepted Answer

Davis-Bacon wage rates are published in wage determinations available through the SAM.gov wage determination database. Rates are set by the U.S. Department of Labor by county, project type (building, heavy, highway or residential) and worker classification (electrician, carpenter, laborer, etc.). The wage determination attached to your contract specifies the minimum hourly rate and fringe benefit rate for each classification. You must use the wage determination that was incorporated into the contract at the time of award. If rates are updated during the project, the contract terms govern which version applies.

Question 15

What are Davis-Bacon overtime rules?

Accepted Answer

The Davis-Bacon Act itself does not mandate overtime pay. Overtime on federal construction contracts is governed by the Contract Work Hours and Safety Standards Act (CWHSSA), which requires contractors to pay at least 1.5 times the basic hourly rate for all hours worked over 40 in a workweek. The basic hourly rate used for CWHSSA overtime is the rate listed in the applicable wage determination, not the regular rate of pay as defined under the FLSA. CWHSSA violations carry liquidated damages in addition to back wages owed.

Question 16

How does prevailing wage overtime differ from standard FLSA overtime?

Accepted Answer

Under the FLSA, overtime is calculated at 1.5 times the employee's regular rate of pay, which includes base wages plus certain other compensation. Under the CWHSSA (which governs overtime on Davis-Bacon projects), overtime is calculated at 1.5 times the basic hourly rate from the applicable wage determination. The basic rate may be higher than the FLSA regular rate, meaning the overtime premium on prevailing wage projects can be larger. Contractors on covered projects must comply with both laws and pay whichever overtime amount is greater.

Question 17

How does certified payroll work for employees on multi-trade projects?

Accepted Answer

When a worker performs multiple trade classifications on the same project, each classification must be reported separately on the WH-347. If a worker spends part of a day as a carpenter and part as a laborer, you must show separate line entries with the correct hours and prevailing wage rate for each classification. Paying the higher classification rate for all hours is permitted, but paying the lower rate for misclassified hours is a violation. Accurate time capture with classification tags at the point of entry is the only reliable way to get this right on mixed-crew job sites.

Question 18

What are the most common certified payroll mistakes?

Accepted Answer

The mistakes that most frequently trigger WHD scrutiny include: incorrect worker classification (reporting a journeyman as a laborer to pay a lower rate), using an outdated wage determination version, submitting an unsigned or missing statement of compliance, late weekly submissions, failing to include fringe benefits in the total wage calculation and misclassifying employees as 1099 independent contractors. The most severe penalty is debarment, which bars the contractor from bidding on federal contracts for up to three years. Back-wage liability and liquidated damages add financial exposure on top of debarment risk. See common certified payroll mistakes that trigger audits.

Question 19

What does certified payroll compliance require?

Accepted Answer

Certified payroll compliance has four core components: weekly submission of WH-347 (or equivalent) to the contracting agency, payment of correct prevailing wage rates by worker classification, a signed statement of compliance on every submission and three-year record retention per 29 C.F.R. § 5.5(a)(3). Beyond these minimums, compliance means maintaining records that can withstand a WHD audit, including daily time records by worker and classification, fringe benefit documentation and proof that apprentices are registered in approved programs.

Question 20

How does automated time capture reduce certified payroll errors?

Accepted Answer

Most WH-347 errors originate upstream of payroll, in the manual step where field hours are reclassified, re-entered or matched to wage determinations after the fact. EasyClocking by WorkEasy Software captures hours with job-cost code, worker classification and project tag at the point of entry on the job site. This eliminates the manual reclassification step that causes the majority of certified payroll errors. When time data arrives in your payroll system already tagged to the correct classification and project, producing an accurate WH-347 becomes a reporting step rather than a reconstruction exercise. The platform integrates with payroll systems so approved hours flow directly without re-entry. For construction-specific details, visit the construction time tracking solutions page.
